perf scripts python: exported-sql-viewer.py: Add context menu

Add a context menu (right-click) that provides options for copying to
clipboard, including, for trees, the ability to copy only the cell under
the mouse pointer.

Committer testing:

$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db

Simply right click and pick "Copy selection", that at this point has
just the first line, not expanded, then see what was copied by pressing
shift+control+v on a terminal:

Call Path,Object,Count,Time (ns),Time (%),Branch Count,Branch Count (%)
▶ simple-retpolin,,,,,,

Ditto after expanding, i.e. the selection continues to be just one
line:

Call Path Object Count Time (ns) Time (%) Branch Count Branch Count (%)
▼ simple-retpolin

Now select all the lines with the mouse and control+shift+v again:

Call Path Object Count Time (ns) Time (%) Branch Count Branch Count (%)
▼ 14503:14503
▼ _start ld-2.28.so 1 156267 100.0 10602 100.0
▶ unknown unknown 1 2276 1.5 1 0.0
▶ _dl_start ld-2.28.so 1 137047 87.7 10088 95.2
▶ _dl_init ld-2.28.so 1 9142 5.9 326 3.1
▼ _start simple-retpoline 1 7457 4.8 182 1.7
▶ unknown unknown 1 805 10.8 1 0.5
▶ __libc_start_main libc-2.28.so 1 6347 85.1 179 98.4
